My computer has a hot part and I don't know what it is

I have installed the package ‘lm-sensors’ and I use the command ‘sensors’ to check the temperature of my computer . The output of the command is something like this:

acpitz-acpi-0
Adapter: ACPI interface
temp1:        +90.0°C

what is “acpitz-acpi-0” . It looks very hot.

It’s the motherboard temperature sensor underneath your CPU. Sometimes that reading is unreliable on Linux because the sensor manufacturer hasn’t released datasheets that are required by developers to read it properly. But in this case 90 seems close enough to

Package id 0:  +86.0°C  (high = +100.0°C, crit = +100.0°C)

it’s time to clean up the fans and replace new thermal-paste.

Or a better CPU cooler.
